barrel 4 by raising the plunger 8. ,It `willbe noted that on the upward stroke of the plunger 8, the suction created therebelow will open the hinged valve 2 and suck the sand into the barrel 4, andwhen the barrel is lled with fluid and sand the suction will cease and the hinged valve 2 will close, thereby retaining the sand in the barrel, the sandpump is then raised to the surface and the hook, as shown in Figure 9, is placed under the lower end of the locking member 5 and pulled outwardly` thereby moving the upper portion of the locking member 5 inwardly out of the slot 3a.k The tubular member 3 isl then turned circumferentially on the tubular member l, until the bosses 1b are even with the slots 3, the tubular member 1 is then removed allowing be emptied.

While it is believed from the foregoing description the nature, operati-on and adthe sand in the barrel 4 to vantages will be readily apparent, I desire to indicate that I do not limit myself yto the specific construction herein shown and described, and that such changes may be rewhen desired, as fall within the What I claim is:

1. In a sand pump in combination with a working barrel and plunger; a slotted cylindrical member rigid upon the lower extremity of the said barrel; a valved cutting member having projections spaced around the peripheryl thereof and arranged to be insert-ed within the slots `of said cylindrical having a stop shoulder; a spring pressed auxiliary locking lever on said cutting member having an upwardly eX- tending finger engageable l with the Stop shoulder to have its outward movement restricted by the said shoulder, the lower end lever being and moved outwardly to move the upper end of the lever inwardly thereby, to permit rotation of the locked members to effect release thereof. l

2. In a sand pump for use yin connection with oil wells and the like, the combination with a working barrel and plunger; a slotted cylindrical member associated Vwith said barrel, a valved cutting member having projections spaced around the periphery thereof and arranged to be inserted within the slots of the said cylindrical member, a locking member associated with said cutting member adapted to engage the Slotted portions of sai-d cylindrical member when in operative position to thereby prevent relative movement of the cutting member with respect to the pump, said locking member being pivotally mounted on the cuttin element and being adapted to be pull outformed to be gripped,

wardly from the bottom thereof to-disengage the same from said slot to permit rotation of the cutting member to effect the release thereof from the cylinder.

, 3. In a sand pump, the combination with a Acylindrical shell constituting the working barrel, of a plunger located within the confines of said barrel, bayonet slots being associated with the lower extremity of the barrel, a valved cutting member having ,projections spaced around the periphery thereofand arranged vertical portions of the bayonet slots and thence rotated intov engagement with the horizontal yportions vof the slots, a locking memberbeing adapted tov engage one of' said vertical slots when the cutting element has been placed in operative position, sai locking member being pivotally mounted on the cutting element adapted to have its lower end moved outwardly from its normal vertical position to move the upper end inwardly thereby, to permitthe rotation of the cutting member with respect to the barrel' to effect release thereof. 4. In a sand pump, the combination with to bel inserted within the l a cylindrical shell constituting the working barrel, a plunger located within said barrel, bayonet slot-s being formed in the lower extremity of the barrel, a valved cutting member having projections spaced around the periphery thereof and arranged to be inserted into the vertical portions of the bayonet slots and thence rotated into engagement withA the horizontal portions in said slots, a vertical slot formed in said cutting member, and coinciding with one of said vertical slots associated with the barrel when the cutting element is in operative position, a locking lever pivotally mounte on the cutting member and being adapted to have its upper` portion engage one of the vertical slots of the relative movement of the cutting element with respect to the barrel, said. locking member beingadapted to have its lower end` moved outwardly from its normal vertical position to thereby move the upper 4end inwardly out of engagement with the slot of the barrel .to thereby permit rotation of the cuttingelementwith respect to the barrel to effect release thereof, and means for preventing the kupper end of the lever from moving outwardly beyond the confines of the barrel. i e

l5. Ina sand pump, the combination with a cylindrical shell constituting thev workingrbarrel, of a .plunger Hlocated within the confines of the barrel, bayonet slots bein formed in the lower extremity of the barre a valved cutting member having projections spaced around the periphery thereof and arranged to portions of the bayonet slots and thence rotated into engagement with the horizontal sai-d barrel to prevent` be inserted `wlthin the vertical 1 portions of the slots in position, a locking lever being adapted to engage one of the vertical slots when the cutting element has been placed into operative position, said locking member having its lower portion vertically disposed Within the confines of the slot of the cutting element and being adapted to be` pulled out- Wardly at its lower end to thereby move its upper end inwardly out of engagement with the bayonet slots to permit rotation of the cutting element with respect to the barrel to effect release thereof.

6. In a sand pump, the combination with a cylindrical shell constituting the working barrel, a slotted cylindrical extension for said barrel rigidly attached thereto, a valved cutting member, said valved cutting member having projections spaced around the periphery thereof and arranged to be inserted within the .slots of the cylindrical member, said cutting element having a slotV in the upper portion thereof, al locking lever pivotally connected with the cutting element within said slot thereof, said pivot for the lever being the lower extremities of the slotted cylindricallmember, said locking member being adapted to engage the slotted portions of the cvlindrical member when in operative position to thereby prevent relative movement of the cutting member with respect to the pump, and normally lying in a vertical position with its upper portion engaging-the slots of the cylindrical member and vthe lower portion of the lever engaging the slot of the valved cutting member, said pivotal placed at a point below locking lever being adapted to be pulled outwardly from the bottom thereof only to disengage the same from the slot of the cylindrical member to permit rotation of the cutting member to effect the release thereof frompthe cylinder.

7. In a sand pump, the combination with a cylindrical shell constituting the working barrel, a slotted cylindrical extension for attached thereto, a valved said barrel rigidly cutting member, said valved cut-ting member having projections spaced around the periphery thereof and arranged `to be inserted within the slots of the cylindrical member, said cutting element having a slot in the upper portion thereqf, a locking lever pivotally connected with the Y cutting element within said slot thereof, said pivot for the lever being placed at a point below the lower extremities of the slotted cylindrical member, said locking member being adapted to engage the slotted portions of the cylindrical member when in operative position to thereby prevent relativermovement of the cutting member with respect to the pump, and normally lying vin a vert-ical position with its upper portion 'engaging the slots of the cylindrical member and the lower portion of the lever engaging the slot of the valved cutting member, said pivotal llocking lever being adapted to be pulled outwardly from thebottom thereof only to disengage the same from the slot of the cylindrical member to permit rotation of the cutting member to effect the release thereof from the cylinder, and means Vfor positively GEORGE J.
